Casting car cover, machine bed and other large mold than traditional sand has a great advantage, it not only eliminates the need for expensive wood-based costs, and ease of operation, shorten the production cycle, improve production efficiency, high dimensional accuracy, allowance is small, good surface quality and other advantages; In addition, casting machining has good wear resistance and anti-shock performance and good process performance. Casting is by melting liquid metal is poured into the mold, the cooling and solidification of parts of the production process to obtain the desired shape and performance. Casting is a common method for manufacturing low cost cable roller, process flexibility, you can get complex shapes and large castings cable roll supply, account for a large proportion of the machinery manufacturing, such as machine tools accounted for 60 to 80 percent, accounting for car 25% of the price of the cable roller, tractor accounted for 50 to 60%. Because now improve the quality of the casting, precision casting, casting and casting cost automation requirements toward precision casting technology, large-scale, high-quality, automation and clean direction, for example, a few years of this technology in precision casting, continuous technical aspects of casting, special casting technology, automation and casting foundry simulation technology is developing rapidly.
